Hi there,
I have a problem (!!)... I'm calling an external fortran routine (that I've
linked as a Windows DLL) using CALL_EXTERNAL with a fortran wrapper. So far
so good with that - when I run the procedure from the IDL prompt I get what
I expect.
When I call it in a loop from within my main program, I get an error "Array
has corrupted descriptor" in (usually) one of the arrays I am returning from
fortran. I'm trying to pin down exactly what is going on - I trawled the web
and found a few mentions to this error occuring when using CALL_EXTERNAL,
but no solutions...
Any ideas / thoughts / suggestions gratefully accepted!
I am running IDL 5.4 under Windows 2000 and calling f77 code compiled and
linked with the Digital fortran compiler.
Regards,
Mark
